Big Rocketeer: Gold

I've made a video on how to complete this achievement:
Darkmoon Faire Achievement: [Big Rocketeer: Gold]

Text from description:

On this track the Power Ups change between the springs that bounce you forward, the teleporter that shoots you forward and the rocket that shoots you up in the air, they cycle around in the order: Spring -> Teleporter -> Rocket. There are 2 rockets you need to take and wait for them to spawn if you have to.

The first rocket you need to take is at 0:16, save the Boosters -Button 1- so you get momentum forward to get on the the ledge, then run up to the highest point and press the Giant Leap -Button 2- to get passed the wall and up to the first banner.

The second rocket is at 1:12, wait for it as I did and use the Giant Leap when you're close to the top.

(You can skip the part from 1:38 and go straight for the finish line)

When you're in the air towards the finish just press 1 and 2 as they come off cooldown.

For anyone who still has to do any of the "The Real Big Race" achievements: Today, I accidentally found an interesting bug that allows you to get them super easily.

1. Pick you "mount" and start the race.
2. Progress through the race normally until you have reached the third and final red post.
3. You don't have to rush, but you need to be at 20 or less tolls by the time you reach the red post. Shouldn't be too hard tho.
4. Next to the red post is a portal that you would normally use to teleport to/from the faire (coordinates circa 51 22). Click the portal. You'll end up back in Elwynn Forest/Mulgore.
5. Once in Elwynn Forest/Mulgore click on the portal to teleport back to the Faire area. The toll timer has now stopped / is deactivated.
6. Make your way back to the starting area of the race. Make sure you approach it from the west, as in pass by the Fishing Supplies stand / Alliance & Horde flags / etc.
7. Pick up your "mount" again and simply run through the finish line.

Keep in mind that this is kinda cheating, so use it at your own discretion.

Good luck! :)

One thing I haven't seen mentioned in the comments yet:

When you're flying towards the finish line, make sure you don't fly over any of the game areas (for instance, the Turtle Ring Toss arena). The game will detect it, and you'll be slammed back down to the ground and stunned for good measure.

Yes, I discovered this the hard way.
